prefrontal cortex
The precentral gyrus is essential for:
fine movements.
Following damage to the temporal lobe, monkeys that fail to display normal fear of snakes most likely have which of the following?
Kluver-Bucy syndrome
One reason why people with prefrontal cortex damage may act impulsively is that they have trouble:

are involved in the same function.
The prefrontal cortex is important for:
working memory.
Cortical blindness may result from the destruction of:

parietal lobe
People with damage of the parietal cortex tend to have trouble ______.
locating objects in space
Individuals with parietal lobe damage:
have difficulty binding the different aspects of perception
What is one important difference between people who are blind because of cortical blindness and others who are blind because of problems with their eyes?
People with damage to their eyes can still imagine visual scenes.
Which of the following is TRUE about the cortical areas that are sometimes known as "association areas"?
They would be better described as additional sensory areas.
Someone who suddenly loses the ability to identify objects by feeling them has probably suffered damage to what area of the cerebral cortex?
parietal lobe
One currently popular hypothesis about the binding problem is that binding depends on:
synchronized activity in different brain areas.
Which of the following is TRUE about laminae in the cerebral cortex?
The laminae vary in thickness in different areas.

cortical blindness.
The area of the brain known to be important for "binding" is the:
parietal cortex
The binding or large-scale integration problem is the difficulty of:
knowing how the visual, auditory, and other areas of your brain work together to create a combined perception of a single object.
Which lobe contains the primary motor cortex and the prefrontal cortex?
frontal
Which lobe seems to be especially involved in the comprehension of spoken language in humans?
